Abstract

The present invention provides an interference pigment that develops interference colors even on light-colored bases. An interference pigment 1 of the present invention includes: a flaky inorganic substrate 10; a transparent metal layer 20 that coats the inorganic substrate 10; and a metal oxide layer 30 that coats the metal layer 20.

First claim

1 . An interference pigment comprising:
a flaky inorganic substrate; a transparent metal layer that coats the inorganic substrate; and a metal oxide layer that coats the metal layer.

2 . The interference pigment according to claim 1 , wherein, when the metal oxide layer is referred to as a first metal oxide layer, the interference pigment further comprises a second metal oxide layer that is formed between the inorganic substrate and the metal layer and that coats the inorganic substrate.

3 . The interference pigment according to claim 1 , wherein the inorganic substrate comprises at least one material selected from the group consisting of glass, mica, silica, and alumina.

4 . The interference pigment according to claim 3 , wherein the material of the inorganic substrate is glass.

5 . The interference pigment according to claim 1 , wherein a metal in the metal layer is one kind metal or a metal alloy.

6 . The interference pigment according to claim 5 , wherein the metal is at least one selected from the group consisting of silver, gold, platinum, and palladium.

7 . The interference pigment according to claim 5 , wherein the metal is at least one selected from the group consisting of silver and gold.

8 . The interference pigment according to claim 1 , wherein the metal layer has an average thickness of 5 nm or less.

9 . The interference pigment according to claim 1 , wherein the metal layer has an average thickness of 2 nm or less.

10 . The interference pigment according to claim 1 , wherein, when the metal oxide layer that coats the metal layer is referred to as a first metal oxide layer, a metal oxide in the first metal oxide layer is at least one selected from the group consisting of titanium oxide, ferric oxide, and iron hydroxide.

11 . The interference pigment according to claim 2 , wherein a metal oxide in the second metal oxide layer is at least one selected from the group consisting of titanium oxide, ferric oxide, and iron hydroxide.

12 . The interference pigment according to claim 10 , wherein the metal oxide in the first metal oxide layer and the metal oxide in the second metal oxide layer are titanium oxide.

13 . The interference pigment according to claim 1 , wherein, when the metal oxide layer that coats the metal layer is referred to as a first metal oxide layer, the first metal oxide layer is coated with a laminated layer comprising one or more transparent metal layers and one or more metal oxide layers that are laminated alternately.

14 . A cosmetic comprising the interference pigment according to claim 1 .

15 . A paint comprising the interference pigment according to claim 1 .

16 . An ink comprising the interference pigment according to claim 1 .

17 . A resin composition comprising the interference pigment according to claim 1 .
